LOCOMOTIVE-BUMPER.

Specification of Letters Patent.

Patented Feb. 13, 1917.

Application filed November 8, 1911, Serial No. 659,186. Renewed July 1, 1916. Serial No. 107,151.

To all whom it may concern.-

Be it known that I, FREDERICK 0. Como, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Locomotive- Bumpers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in vertically adjustable bumpers for locomotives. It is particularly applicable to bumpers such as are mounted upon the end frames of electric mining locomotives.

An object of the invention is the provision of a vertically adjustable bumper and coupler such as may be readily mounted upon the end frame of a locomotive and easily adjusted in a vertical plane. When using a locomotive with cars of different constructions it is oftentimes found necessary to vary the height of the point at which the coupling is connected to the locomotive. In the commoner types of buffers provision is made for this adjustment by forming a series of vertically arranged pockets in the bumper within any one of which the coupling links may be inserted. It is evident that the increments of adjustment are, in this type of bumper, definitely determined and if it is found desirable to attach a coupling link to the locomotive at a point in termediate any two of the pockets, it is necessary to entirely remove the bumper from the locomotive and drill a new set of holes in the end frame for the attachment bolts.

My invention greatly simplifies the adjustment of a bumper to the end frame of a locomotive and furthermore greatly increases the accuracy in locating the bumper for a particular height of coupling.

In the drawings,

Figure I is a front elevation of my improved bumper.

Fig. II is a plan view.

Fig. III is a vertical sectional view on the line A-A of Fig. I.

Fig. IV is a vertical sectional view on the line BB of Fig. I.

Fig. V is a front elevation of two adjusting plates.

In the drawings, the numeral 1 indicates one of the side frames of a locomotive. To

the ends of the side frames, only one of which is shown in the drawing, are at tached connecting angles 2 which carry the connecting piece or end frame 3.

A cast ironbumper indicated in general by the numeral 4 has formed in the central portion of its face a vertical series of pockets 5 adapted to receive a coupling link 6. A vertical hole is drilled through the webs 7 formed between the pockets so that a bolt or pin 8 may be inserted, thereby coupling the link 6 to the bumper. Over-hanging lips 9 of the usual type are formed on the upper portion of the bumper at each side of the pockets In order to attach the bumper to the end frame of the locomotive four attachment bolts 10 are provided. Vertical elongated holes or slots 11 are formed in the cast bumper at each side of the pockets 5 and are adapted to receive the attachment bolts 10. Vertically arranged pockets 12 are countersunk in the face of the bumper and embrace the slots 11. The openings 12 are formed so as to receive the heads of the bolts 10. Two of the bolts are passed through the slots in the bumper in vertical alinement with one another at each side of the pockets 5.

It is obvious that the slots formed in the bumper will allow of its vertical adjustment, but on the other hand, that the friction produced by tightening the bolts and pressing the cast iron washers 13 against the edges of the slots 11 would not be suflicient to hold the bumper in place. To overcome this ditliculty I have formed recesses in the back of the bumper in line with the slots 11 and placed therein the two adjustment plates 14. Each adjustment plate has a pair of holes drilled to receive the attachment bolts 10, the holes being spaced a distance apart equal to the distance between the bolt holes formed in the end frame. When the plates are inserted in the rear of the bumper, the bolts may be placed through the end frame, the plates and the bumper, then tightened. This will securely hold the bumper to the end frame at a particular point. If it is found necessary to vary the height of the bumper, new plates may be inserted having the centers of the holes shifted, either up or down depending on the new position in which it is desired to locate the bumper.

In cases Where the increment of adjustment is apt to be greater than the diameter of the bolts, plates may be furnished in which several sets of holes are drilled. Such a plate is illustrated in Fig. V.

To provide a slight cushioning of the bumper I have inserted a Wooden plank 15 between it and the end frame 3. Holes are formed in the plank which register With the bolt holes in the end frame.

hat I claim is:

1. In combination With a bumper of the type described, having vertical bolt receiving slots formed therein and provided with a recess in the back thereof, of a plate adapted to fit Within said recess and provided with bolt holes, and attachment bolts for said bumper.

2. In combination with a bumper of the type described, having vertical bolt receive ing slots formed therein and provided With a recess in the back thereof of a plate adapted to fit Within said recess and provided with a vertically arranged series of bolt holes, and attachment bolts for said bumper.

In testimony whereof I affix my signature, in presence of two Witnesses.
